How to Use Mini AC-DC 110V-230V to 5V 700mA Module: Examples, Pinouts, and Specs

The Mini AC-DC 110V-230V to 5V 700mA Converter Module by PermanentFly is a compact power supply module that converts high-voltage AC power to a low-voltage 5V DC output. This module is ideal for powering 5V DC electronics from a standard AC power supply and is commonly used in DIY projects, IoT devices, and small household electronics.

• Powering microcontrollers like Arduino or Raspberry Pi
• Supplying power to LED lighting systems
• Operating low-power sensors and modules in home automation
• Providing 5V DC to USB-powered devices

• Input Voltage: 110V-230V AC
• Output Voltage: 5V DC
• Maximum Output Current: 700mA
• Isolation Voltage: >1000V
• Operating Temperature: -20°C to 60°C
• Efficiency: >70%

1. AC Input Connection:

   • Connect the live wire (L) from the AC mains to pin 1.
   • Connect the neutral wire (N) from the AC mains to pin 2.

2. DC Output Connection:

   • Connect the positive terminal of your device to pin 3 for the 5V output.
   • Connect the ground terminal of your device to pin 4.

• Ensure the module is properly insulated to prevent electrical shock.
• Verify the input voltage range before connecting to the AC mains.
• Do not exceed the maximum output current of 700mA.
• Use a fuse on the AC input for additional safety.
• Avoid placing the module in high-temperature environments.
• Double-check wiring to prevent short circuits or incorrect connections.

• Insufficient Output Current: Ensure that the total current draw of the connected devices does not exceed 700mA.
• Overheating: If the module is overheating, check if the current draw is within limits and provide adequate ventilation.
• No Output Voltage: Check AC input connections and ensure the module is not damaged.

• Always start by checking the connections and ensuring that the input voltage is within the specified range.
• If the output voltage is unstable or there is no output, inspect the module for any signs of physical damage.
• Use a multimeter to verify the output voltage and current to ensure they are within specifications.

Q: Can I use this module to power a USB device? A: Yes, as long as the device operates at 5V and requires less than 700mA.

Q: Is this module isolated? A: Yes, it has an isolation voltage of over 1000V, but always handle with care.

Q: Can I connect multiple devices to this module? A: Yes, multiple devices can be connected as long as their combined current draw does not exceed 700mA.

// This example demonstrates how to power an Arduino UNO using the Mini AC-DC Converter Module.

void setup() {
  // Initialize the digital pin as an output.
  pinMode(LED_BUILTIN, OUTPUT); // Most Arduinos have an on-board LED on pin 13
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH);   // Turn the LED on
  delay(1000);                       // Wait for a second
  digitalWrite(LED_BUILTIN, LOW);    // Turn the LED off
  delay(1000);                       // Wait for a second
}

// Note: The above code does not interact with the power module directly.
// It assumes that the Arduino is being powered by the 5V output from the module.
